AoETYLENE-GAS eENEizA'ron To'aZZ-tvhom t may concern:

u .LIAM MINTER, and

. useful Improvements in Acetylene-Gas Genwhereby gas for craters, of which 'the following isa speciication, reference being had to the aecom panying drawings; v This invention relates to improvements in acetylene gas generators and has Jfor its-primary object to provide a simple and positively acting. apparatus of t-his character illuminating or other purposes may be inexpensively manufactured.-

Another and more specific object of the invention resides in the provision. of means l.for automatically supplying Waterto the movable closure generator whereby, the carbid is converted into gas.

.Another object of the invention is to 'provide a gas generating yapparatus of the above described character including` in combination a generator' and gasometer, a gas supply pipe,'connecting the same, a water feed pipe connected to the generator, and a movable supply pipe connected to the gasoineter andmeansto automatically move the same upon the increase of gas pressure whereby the supply oit Water ,to the genen .ttor is automatically cut ott.

With the above and other objects in view, the invention consists of the novel features or' construction', combination and arrangement of parts hereinafter t'ully described and claimed, and illustrated in the accompanying drawings, in whicl Figure 1 is a perspective view of our improved gas Agenerating apparatus showing the parts as arranged in the process ot' gas Inanuiacture; Fig. 2 is a vertical section ot' the generator.

Referring in detail to the'drawings 5 des ignates the generator which'consists ot the spaced concentric 'outer and inner shells 5 and 6 respectively and 7 designates a reior the outel shcllwhich incliides a tubular ceived in the space between said outer and inner shells. rlh'is space is filled with Water as shown. To the top 7 ot the generator a nipple 9 is secured which is disposed centrally in said top and above the upper open end ot the inner shell 6. A coupling or Speccat'onbf Letters latent.

union v10 connects this nipple to the pipe gasometer Where itv shell 6 ot the generator is filled with. carbid as' indicated fat 12 to which water is supplied through the. medium of the pi-pe 13 -Which is connected to the gas coitlut'ng pipe 11 as clearly shontn in- Fig. 1.-

. The gasometer consists of a cylindrical vessel 14 which is'proportionate in size to the generator -5 and in .accordance With the gas generating capacity thereof.. A bell 15 -is vertically movable in sel Which is filled withl Water to provide a seal for the lower open end-ot the bell. The gas conducting pipe 11 extends from the generator 5 and extends centrally through the bottom of the gasometer' shell 14, said pipe having a Water drain valve 1G therein and a gas controlling valve or cock 17. The upper closed end ot the gas bell 1,5 carries the perforated brackets 18 which loosely receive the vertical guide rods 19 Aarranged at diametrically opposite points upon the gasonieter and are preferably secured to the periphery of the shell 14. One of Athe ver tical guide members 19 may be in the form of a pipe and connected to the gas pipe 11, the u per end et said,vertical v'pipe being provi ed with a suitable tip as shown at 19V whereby the cella-r or other compartment wherein the apparatus is loca-ted may be illuminated without necessitating the provision of `a separate service pipe.

-A service pipe 20 isconnected to the conducting-pipe 11, said service pipe being extended along the Walls of the building and. through the various apartments thereof. The pipe 11 has a vertically disposed portion (not shown) extending through theY bottom this cylindrical ves A 11 which conducts the generated gas to the is purified. The inner esv of the shell 14 ot the gasometer and having its upper open end disposed above the level of the water therein to discharge the gas into the upper portion ofthe bell 15. Y

The water feed pipe 13 for the generator 1 l, is located adJacent to the gasoxneter and is E end. with a.: tunnel Ol i 22 is coii1iected,s'aidpipe being' rotatably l mounted in the wall of said shell at one end and provided upon its other end with a cock or faucet 23 ,whereb i the Water supplyniay l be conveniently controlled. Upon the wall l or other permanent support ajpieceof lboard To theshell 15. 4onefend lof' asnpplyr pipe l0@l has a vertically extended portion 13 which position shown in Fig. l,

or plank indicated at 24 is'securely fastened and upon the same a rod 25 is rotatably mounted in suitable-bearings. One end of this rod is bent at a. right angle and forwardly extended as indicated at 26 and has connected thereto The other end of the rod 25 is also forwardly extended and provided with a curved or hooked extremity-as indicated at 28. This curved end of the rod bears against the edge of the upper closed end of the movable gas bell l5 and as this gas bell is raised by the pressure of gas therein, it will be obvious that the rod or its bearings, and through the medium of the angularly disposed end portion 26 thereof and the connecting wire 2T, the water supply pipe '22 will be swung upwardly to the position shown in Fig. 2. l

From the foregoing it is thought that the 4 construct-ion and manner of operation of our of the rock shaft 25 at Contact with said bell. bid for the generator newed by disconnecting generator from the gas pipe ll by the nia-2 nipulation of the coupling l0. The pipe'22 discharges the water from the gasometer into the funnel 2l on the upper end of the water feed pipe 18. Thus the generator is Aat all timesautomatically kept supplied with water so that as soon as the gas pressure in the gasometer is diminished to the proper point, the supply of water to the one end of a wire 27, the other end of which is connected to the lrotatably mounted water vsupply pipe 22.

shaft 25 will be rocked in carbid 'in the generator` is renewed and the generation of .gas restablished. A device constructed in accordance with expensively manufactured and and reliable in practical-operation. paratus is also durable in construction and by means of the same a constant gas supply may be maintained at an insignificant cost.

While we have shown and described the4 preferred form and arrangement of the vari ous elements, it will be understood that the invention is `susceptible of considerable modication Without departing from the essential feature or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is z* In an acetylene gas generator, the combi`- nation wit-h a generating vessel, Aa gasometer and a gas conducting pipe 'connecting said4 generator and gasometer, of a water feed pipe for the generator havinga, vertically isposed portion open at its upper end,

ing shell tatably mounted rod having one of its ends engaged with said bell, the other end of said- A.the present invention is simple, may be in'v is' 'positiveV The ap said gasometer including an .outer water contain-v and a bell movable therein, a ro-l rod being bent at right angles, and a flexible Y connection between said latter end of the pipe whereby said suprod and said supply ply pipe is elevated upon the increase of gas pressure to cut generator.

In testimony whereof we hereunto afiix' our signatures in the presence of two wit? nesses.
